What is pseudopolynomial time? How does it differ from polynomial time?
...ssibly a lot faster.
In 2004, three computer scientists published a paper called PRIMES is in P giving a polynomial-time algorithm for testing whether a number is prime. It was considered a landmark result. So what's the big deal? Don't we already have a polynomial-time algorithm for this, namely t...
How to get the mysql table columns data type?

Is the practice of returning a C++ reference variable evil?
